Evolution of the Fluid System During the Formation of the Fault-Related Bóixols Anticline (Southern Pyrenees)
Structural, petrological and geochemical data allow us to constrain the fluid flow system at the frontal part of the Bóixols thrust sheet, Southern Pyrenees, focusing on the fluid origin, pathways and regimes. Throughout the evolution process of the fault-related Bóixols anticline, different fracture sets have been developed and mineralized with at least four generation of calcite cements. Such developments testify that such structures allowed the migration and interaction of four types of fluids during the early contraction, the syn folding stage and the latest folding stages.
